# adc for someone with admin privs to invoke "expand" on other users.

# This doc block as "WHY", "HOW", and "CAVEATS" sections; I mention that only
# for those people with very small xterms who may miss the CAVEATS section
# otherwise...!

# WHY
# ===

    # ...because info has it, and expand doesn't :-)

    # (Possible question: Why not add that capability to expand instead to be
    # consistent?  Probable answer: how about we go the other way and make
    # "info" also work like this, and remove that code from core?  I like
    # having less less code in core!)

# HOW
# ===

    #   ssh gitolite su-expand . user1 user2 user3

    # note that the first argument is still treated as a "pattern", so at
    # least put in a "." for a catch-all pattern.  Also see caveats for
    # patterns below.

    # This will output the same thing as "ssh git@server expand ." performed
    # by the individual users

# CAVEATS
# =======

# (1) LIMITS TO THE PATTERN

    # Due to this being an ADC, and ADC arguments being very, Very, VERY,
    # stricly limited, you won't be able to use any regex meta characters
    # expect ".".  I'll worry about changing it if enough people complain.

# (2) NAME OF THIS SCRIPT

    # please name this script something other than "expand", because we can't
    # have name clashes between internal commands (info, expand,
    # (get|set)(perms|desc), etc) and admin-defined (external) commands.  I'm
    # calling it su-expand; feel free to change it.
